Biology

Psyduck is a yellow Pokémon that resembles a duck or bipedal platypus. Three tufts of black hair grow on top of its head, and it has a wide, flat, cream-colored beak and vacant eyes. Its legs, arms, and tail are stubby and its webbed feet are cream-colored. There are three claws on both of its hands.

Psyduck is constantly stunned by its headache and is unable to think very clearly. It usually stands immobile, trying to calm its headache. However, when its headache becomes too severe, it releases tension in the form of strong psychic powers. The use of these powers produces brain waves identical to those seen in sleepers, and the Pokémon is unable to recall these episodes. Psyduck lives in freshwater lakes, small ponds, or rivers in tropical areas.

In the anime

Major appearances

Misty has a Psyduck that she accidentally caught in Hypno's Naptime. It is a constant source of frustration for her, as it frequently emerges from its Poké Ball to attempt to battle the opponent in substitution of one of her other Pokémon. Despite this, she has been shown to deeply care for it. Despite being generally shown as dimwitted and oblivious, when its headache gets bad enough, it has been shown to use phenomenally powerful Psychic-type moves which far exceed its normal ability.

In the movie adaptations

In the Pokémon Adventures manga

In the Red, Green & Blue chapter, an undead Psyduck that had been brought back to life by a Koga's Gastly appeared in the Pokémon Tower. It first appeared to Red like a normal Psyduck, until it attempted an assault on him: its eyeballs suddenly sunk into its eye sockets and some skin fell off, revealing its bones. Since it was just a mindless undead, it was easily destroyed by Red's Bulbasaur using Vine Whip.

After several other appearances, a herd of Psyduck appeared, blocking the route to Celestic Town, just as they had in the games. However, included among them were Trainer Pokémon, and this was all a ruse by Team Galactic, which Cynthia catches on to shortly after calming them.
